Abstract
The hydrodynamic stability of thin condensate films adjacent to flowing vapors is considered. The conditions representing mass, momentum, and energy conservation across the liquid/vapor interface are formulated for the case of negligibly small vapor hydrodynamic boundary layer thickness. The problem formulation is analyzed by means of a perturbation method yielding the base flow problem and the linearized stability problem. The linearized stability problem is analyzed yielding the neutral stability curves and closed form approximate expressions for the wave amplification rates and the wave velocities. The results of the stability analysis are discussed with reference to forced vapor flow condensation on vertical and horizontal surfaces. The effects of vapor velocity, density ratio, Prandtl number, acceleration effect parameter and the surface tension parameter on the stability characteristics of infinitesimal disturbances are identified.
